Abstract:
The authors present the possibilities of obtaining tissue samples with stereotactic biopsy basing on three examples of intracranial polymorphic and invisible in CT tumours. CT scans of these tumours make a serious problem with proper targeting and tissue sampling from proper sites. Stereotactic serial biopsy directed by CT/MRI fusion is the best way of obtaining tissue material in order to establish correct diagnosis.
Insights
Stereotactic biopsy, guided by CT/MRI fusion, offers a reliable method for obtaining tissue samples from challenging intracranial tumors. This technique is crucial for accurate diagnosis when tumors are difficult to visualize on CT scans alone.
Area of Science:
- Neurosurgery
- Neuroradiology
- Oncology
Background:
- Accurate diagnosis of intracranial tumors relies on obtaining adequate tissue samples.
- Polymorphic and CT-invisible tumors present significant challenges for conventional biopsy targeting.
- Stereotactic biopsy offers a minimally invasive approach for tissue acquisition.
Observation:
- Three cases of intracranial polymorphic and CT-invisible tumors were analyzed.
- CT scans alone provided insufficient information for precise tumor targeting and sampling.
- CT/MRI fusion imaging was utilized to enhance spatial localization.
Findings:
- Stereotactic serial biopsy, directed by CT/MRI fusion, enabled precise tissue sampling.
- This approach successfully overcame the limitations of CT-based targeting for difficult tumors.
- Histopathological analysis of obtained samples led to correct diagnoses.
Implications:
- CT/MRI fusion-guided stereotactic biopsy is a valuable technique for diagnosing complex intracranial neoplasms.
- This method improves diagnostic yield in cases where tumors are poorly delineated on CT.
- Enhanced diagnostic accuracy facilitates appropriate treatment planning for patients with brain tumors.
